Abstract: 22,904. Shepherd, D. Oct. 21. Tables; castors.-An operating-table, Fig. 1, is constructed of a tubular metal framing a and a body support b, b<1>. Hinged to one end of the latter is a head-rest c, and to the other end are pivoted leg-supports d, d<1> by means of movable bolts e. The inclinations of the rest and supports are adjusted by means of ratchets f, provided with springs f<1>, to keep their forward ends engaged with ratchet teeth, and handles f<3>. The legs of the table may be raised from the ground by means of levers g, Fig. 5, pivoted at g<1>; each lever is provided with a toothed quadrant g<2>, which gears with a rack i formed on a wedge i<1>; this wedge is connected by a tube i<2> with a second wedge i<3>. The inclined edges of the wedges press upon rollers j supported by rods k<1> and springs k<2> which slide inside the legs a'. The lower ends of the rods are screwed to rings k<4>, which support circular blocks m fitted with ball bearings. At the sides of the blocks are mounted rubbertyred rollers m<2>, which act as castors when forced on the ground, by the levers for raising the legs. Pivoted catches hold the levers in their actuated positions. The frames b, b<1>, Fig. 6, are pivoted at b<2>, and may be raised to assume the Trendelenberg position by means of a screw-threaded rod n, pivoted to the frame b, which engages with a nut attached to a bevel gearing n<2> ' n<3> operated by a handle o. The frame b<1> is pivoted to slotted T-pieces b<4> capable of sliding on guide-bars a<4> fixed to the framing a, and may be supported at an angle by a rack b<6>, Fig. 7, which engages with teeth b<7> fixed to a cross-stay. In the horizontal position, the frame b, Fig. 1, is supported by studs a<6>, and the frame b<1> by guide-bars a<4> and pivotal joints b<2>. The upper portion of the table may be raised by screw-rods, which are connected with the cross-framing and engage with nuts operated by worm-wheels. The worm-wheels and nuts are enclosed in boxes q, Fig. 1.

Patent GB-190301218-A (GB)
Title: Safety Coupling for Change Speeds in Motor Cars.
Inventor: CROUAN HENRY
Filed: 1903-01-17
Granted: 1904-01-07
Abstract: 1218. Crouan, H. Jan. 17. Motor road vehicles.-Relates to change speed gear, and consists of an arrangement for preventing the gear from being changed unless the motor is uncoupled. The lever F, pivoted to the shaft T, carries a sleeve E and, on the other arm, a tongue K fitting into recesses cut in the wheel R connected with the change speed gear. The tongue prevents motion of the wheel unless it is disconnected by the foot-lever P, which, at the same time, moves the sleeve E and uncouples the motor. Between the main recesses in the wheel R corresponding to change of speed, intermediate recesses are cut, thus preventing the sudden recoupling which would occur if the tongue could slide along the wheel and suddenly drop into a main recess. A similar arrangement is described in which a rectilinear form of rack is used.

In the form shown in Figs. 3 and 4, the stopper is made from a cylindrical plug a, preferably of soft wood, and slightly larger in diameter than the narrowest part of the bottle neck. Saw-cuts b are formed in the plug, each preferably at an angle of about 70‹ to the tangent at the point where the cut is made. The cuts may, however, be made radially. The stopper may be protected, where it is inserted in the neck, by a capsule c of soft metal, gutta-percha, or other waterproof material, the uncovered part of the plug being treated with a waterproofing-agent ; or, the plug may be entirely covered with two overlapping capsules &c, A layer e of cloth, felt, &c. may be inserted between the plug and the capsule. A recess f is formed in the top of the plug, to receive a corkscrew for extracting the stopper. Fig. 7 shows a stopper made of a coiled roll of paper, which is preferably corrugated, and covered by a capsule c. When a capsule is not employed, the axial hole in the stopper is closed by a plug of cord &c., or by compressing the stopper longitudinally. Stoppers may also be made of paper pulp, wood pulp, &c.

Granted: 1904-12-08
Abstract: 6929. Nuttall, W., and Pearson, C. H. March 22. Stopping engines and trains.-In an arrangement whereby tramcars and other vehicles are stopped on meeting an obstacle on the track, the displacement of a swinging gate h, Fig. 1, besides lowering the life-guard q, releases a lever o, a piece 12 on which, by means of a chain 13. pulls back a slide 14 connected to the switches, and cuts off the current from the motor. At the same time, the fall of the life-guard causes brake blocks 6 to be applied automatically to the wheels. The lever o is pressed from behind by a spring w, but is kept in its ordinary position by a notch n, Fig. 5, which rests on a rod m fixed to the swinging gate above its pivot g, Fig. 1. The slide 14 is replaced from a foot-rod 16 through a bell-crank lever 17 and a rod 19. In a modification, the lever o is replaced by a bell-crank lever 21, Fig. 6, which is connected to a lever 28 on a cross shaft p by a tube 26 having short rods screwed on at its ends. More than one spring w may be used. When applied to a bogietruck car, the actua ing-spring may either be placed as before or between the lever o and the bottom of the car, as at 48, Fig. 7. When the arrangement is applied to both ends of the car, only one slide 14, Fig. 9, is used, it being drawn from the other end by a chain 49 passing over a pulley 50. It is closed from that end by a r d 51 and lever 52.

Title: Improvements relating to Sulphur-compounds and to Priming or Igniting Compositions suitable for the Manufacture of Matches.
Inventor: WETTER JASPER
Filed: 1904-04-05
Granted: 1905-02-09
Abstract: 7893. Wetter, J., [Riedel, Firm of, J. D.]. April 5. Matches.-Phosphorus in igniting-compositions is replaced by compounds of sulphur with polythionates or "sulpho polythionates." The polythionates, such as cupro-barium polythionate, are produced by the oxidation of thiosulphates with cupric salts, or with chloride of iron, iodine, or other oxidizing-agents, and precipitation with barium or other suitable salts. The precipitate is intimately mixed with sulphur and submitted to pressure or to dry or moist heat. In another method, a soluble thiosulphate is precipitated by a barium or other salt, preferably in the presence of a small quantity of a salt of bismuth, zinc, or other metal whose thiosulphate is soluble. The precipitate is washed and mixed with finely.divided sulphur and with a solution of a cupric salt, whereby sulpho-polythionate are formed.
